PARALYSIS. 407 
-administer 10 or 20 grammes of iodide of potassium. As soon as im- 
provement appears, short walks, morning and evening, gradually increased, 
-are beneficial. Subcutaneous injections of strychnine (0 gr. 025-0 gr. 05), 
-or of veratine (o grs. 10), made in the affected region, are recommended, 
by Bormann and Miller. Those of salt water or spirits of turpentine may 
-also be useful. 
The treatment of incomplete paralysis is the same. The animal should 
be put in slings or left loose in a box-stall; locally, revulsives and blisters 
‘should be used. 
LV.—Obturator Nerve. 
This is generally mentioned only as consecutive accident of dystokial 
labors and fractures of the pelvis: it is produced by active pressures made 
‘upon the nerve on some points of its course, most commonly at the 
obturator foramen, either during the passage of the foetus or by effused 
blood or again by a large callus. In all species, it may also be due to 
neoplasm of the neighborhood of the nerve; it has also been observed in 
white horses affected with melanosis of the pelvis. 
At rest, the leg is carried more or less in abduction, the joints are 
flexed, the toe of the foot turned outwards. In walking, the extremity is 
moved with difficulty and with a motion of abduction. Little by little 
there is atrophy of the muscles where the nerve ramifies—adductors of 
the thigh, pectineus, short adductor of the leg. This atrophy with the 
-conditions detected by rectal examination confirm the diagnosis. 
Against paralysis due to tumors or a callus, there is nothing to do. 
For those of dystokial origin, “irritating frictions on the croup and thigh” 
have been recommended. Cold irrigations of the vagina and massage. 
through its walls should be more efficacious. At times improvement 
occurs rapidly, even when no treatment is carried out ; quite often the 
lameness does not disappear for months, sometimes it remains permanent. 
V.— Femoral Nerve. 
It is no doubt to “ hemoglobinuria ” or “ congestion of the spinal cord”: 
that most cases of femoral paralysis are due. Goubaux, Bouley, Reynal 
saw in it the consequence of rupture of the “psoas, which is “of such: 
dlelicate texture that it tears with the greatest facility, during life as after. 
death” (Rigot). But paralysis of the triceps cruralis may appear at the 
-onset of the disease, and at the autopsies of a// the horses which had it, no 
lesions of the psoas could be found. In these cases it was either a myo- 
pathic paralysis, or a femoral neuritis, due, as myositis are, to rheumatismal 
or infectious process.
